+#
+# Interactive script for sending a collection of Mercurial changesets
+# as a series of patch emails.
+#
+# The series is started off with a "[PATCH 0 of N]" introduction,
+# which describes the series as a whole.
+#
+# Each patch email has a Subject line of "[PATCH M of N] ...", using
+# the first line of the changeset description as the subject text.
+# The message contains two or three body parts:
+#
+#   The remainder of the changeset description.
+#
+#   If the diffstat program is installed, the result of running
+#   diffstat on the patch.
+#
+#   The patch itself, as generated by "hg export".
+#
+# Each message refers to all of its predecessors using the In-Reply-To
+# and References headers, so they will show up as a sequence in
+# threaded mail and news readers, and in mail archives.
+#
+# For each changeset, you will be prompted with a diffstat summary and
+# the changeset summary, so you can be sure you are sending the right
+# changes.
+#
+# It is best to run this script with the "-n" (test only) flag before
+# firing it up "for real", in which case it will display each of the
+# messages that it would send.
+#
+# To configure a default mail host, add a section like this to your
+# hgrc file:
+#
+# [smtp]
+# host = my_mail_host
+# port = 1025
